What is the difference between an exothermic and exergonic reaction in terms of energy release and spontaneity?
An exothermic reaction releases energy in the form of heat, while an exergonic reaction releases energy in the form of free energy. Both reactions are spontaneous, meaning they occur without needing an external energy source.
What is the difference between endergonic and exergonic reactions in terms of energy changes?
Endergonic reactions require an input of energy to occur, while exergonic reactions release energy.
What is the difference between exothermic and exergonic?
exergonic reaction is a chemical reaction that releases free energy. its final state is less than its initial state. while the endergonic reaction is a chemical reaction that absorbs free energy from its surroundings. in this process, the initial state is less than its final state. it does not occur spontaneously.
What is the relationship between the formation reactions that are exothermic and their corresponding enthalpy of formation values (hf)?
The relationship between exothermic formation reactions and their enthalpy of formation values is that exothermic reactions release heat energy when the compound is formed. This results in a negative enthalpy of formation value (hf) because the reaction is giving off energy.
What makes combustion reactions so common and proceed so readily?
Combustion reactions are common and proceed readily because they involve highly exothermic reactions between a fuel and an oxidizing agent. This leads to the rapid release of heat and light, making the reaction self-sustaining. Additionally, many fuels used in combustion reactions, such as hydrocarbons, have high energy content, making the reactions very exergonic.

What is the difference between exothermic and exergonic?
exergonic reaction is a chemical reaction that releases free energy. its final state is less than its initial state. while the endergonic reaction is a chemical reaction that absorbs free energy from its surroundings. in this process, the initial state is less than its final state. it does not occur spontaneously.
Compare and contrast between exergonic and endergonic reactions?
Exergonic vs. Endergonic reactions: exergonic release more energy than they absorb. Endergonic reactions absorb more energy than they release.Exergonic reactions release energy while endergonic reactions absorb energy.
What is the diffrencence between exothermic reaction and chemical reaction?
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
What is the relationship between exergonic reactions endergonic reactions and the use and regeneration of ATP?
Exergonic reactions release energy and are spontaneous, while endergonic reactions require energy input and are non-spontaneous. ATP is used to drive endergonic reactions by providing the necessary energy for them to occur. ATP is regenerated through exergonic reactions by capturing the energy released during these reactions.
What is the difference between endothermic and exothermic?
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
What is an exergonic reaction?
Exergonic reactions indicate a negative change in Gibbs free energy, which in English means that the reactions are spontaneous and do not require addition of energy. The exchange of oxygen and carbon dioxide in blood and lungs is an example. It is the concentration gradient that runs these exchanges passively, without additional energy from the cells.
What is the relationship between the formation reactions that are exothermic and their corresponding enthalpy of formation values (hf)?
The relationship between exothermic formation reactions and their enthalpy of formation values is that exothermic reactions release heat energy when the compound is formed. This results in a negative enthalpy of formation value (hf) because the reaction is giving off energy.
What is the reaction of sodium bicarbonate and hydrochloric acid is endothermic or exothermic?
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
What are some example of exothermic reaction?
Exothermic Chemical Reactions · mixing sodium and chlorine to yield table salt · Respiration; combustion of fuels; and neutralization reactions between acids and alkali's
